Description

[Detailed Description of the Invention] The present invention relates to a tightening fitting for a utility pole band, which is used to attach a conduit, a ground wire, a reflector, etc. to a utility pole using a band.

Conventionally, this type of tightening fitting for utility pole bands has been formed by combining a plurality of separate members, and therefore has the drawback that tightening of the band is time consuming and has poor workability. This method has the disadvantage that work efficiency decreases, especially when working at high places such as utility poles. Furthermore, since the band tightening portion remains exposed, it is easily tampered with.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and as a result, provides a tightening fitting for a utility pole band that eliminates the above-mentioned drawbacks.

The present invention will be described below with reference to the drawings.

In the drawing, A is the fastening fitting of the present invention,
It is made from sheet metal. Tightening fitting A is the first
As shown in the figure, the board 1 and the clamping plate 2 are integrally and continuously provided, and the clamping plate 2 is bent in the direction of the arrow in FIG. being done.

The outer peripheral edge of the substrate 1 except for the connecting portion with the clamping plate 2 is bent to the back side to provide a bent edge 11.
Further, the substrate 1 is provided with an insertion hole 12 for fixing one end of the band 3, an insertion hole 13 for fixing the other end of the band 3, and a protrusion 14 arranged side by side. A plurality of insertion holes 12 are provided, and at least one insertion hole 13 and at least one protrusion 14 are provided, and the insertion hole 1 extends from one end of the substrate 1 to the other end.
2, 13, and cut and raised protrusions 14 are arranged in this order. Further, as shown in FIG. 4, the insertion holes 13 may be communicated with adjacent insertion holes 12.

The tightening plate 2 is large enough to cover the board 1, and has a protrusion 2 that fits into one insertion hole 12 of the board 1.
1 is provided or a bent edge 1 of the substrate 1 is provided on the outer peripheral edge.
A bent edge 22 that fits into the band 1 is provided, and the band 3 can be tightened by the convex portion 21 or the bent edge 22 when bent, as will be described later. or,
23 is the bent edge 11' of the board 1 when the clamping plate 2 is bent.
It is a hook-shaped locking piece that can be locked to. It is preferable for the clamping plate 2 to form a substantially right angle to the substrate 1 as shown in FIG. 1, since this makes it easier to bend, but it may also simply be continuous with the substrate 1 in the form of a flat plate.

Next, a method of using the fastening fitting A of the present invention will be explained.

First, to explain the case shown in FIGS. 2 and 3, the board 1 is brought into contact with the utility pole 4, one end 31 of the band 3 wrapped around the utility pole 4 is inserted into the insertion hole 12 of the board 1 and bent, and the band 3 is bent. The other end 32 is inserted into the cut and raised protrusion 14 and the insertion hole 13 of the substrate 1 and bent. Next, the other end 32 of the band 3 is cut and raised while being pulled, and the protrusion 14 is crushed by hitting with a hammer or the like, and the other end 32 is fixed as shown in FIG. Next, the clamping plate 2 is bent and fitted onto the board 1, and the locking piece 23 is locked to the bent edge 11' of the board 1. That is, as shown in FIG. 3, when bent, the protrusion 21 of the tightening plate 2 is fitted into the other insertion hole 12 adjacent to the insertion hole 12 through which the one end 31 of the band 3 is inserted, and the protrusion 21 closes the insertion hole. One end 31 of the band 3 is pushed into 12 and the band 3 is tightened.

The case in FIG. 4 is the same as the case in FIGS. 2 and 3 above, and one end 31 and the other end 32 of the band 3
It is inserted through the insertion holes 12 and 13 that communicate with each other.

Furthermore, in the case of FIG. 5, the convex portion 2 of FIG.
1, the band 3 is tightened by the bent edge 22 of the tightening plate 2. In this case, when the tightening plate 2 is bent, the bent edge 22 is fitted into the bent edge 11 of the substrate 1, and the band 3 is tightened from one end 31 and the other end 32 of the band 3.

As described in detail above, the present invention's fastening fitting has a board and a fastening plate that are integrally and continuously provided, and the fastening plate bends at the connection part with the board and is fitted and locked to the board. There is no need to combine a plurality of members as shown in the figure, and the band can be tightened with a single metal fitting, which improves work efficiency, especially at high places such as utility poles.

In addition, the band insertion hole and cut protrusion are provided on the board, and the band is tightened by bending the tightening plate and fitting it to the board, so it can be cut and protruded using a simple tool such as a hammer. The ends of the band can be temporarily tightened by crushing the ends, and the band can be fully tightened by bending the tightening plate.

Furthermore, since the tightening plate is large enough to cover the board and is bent to fit and lock onto the board, the end fixed part of the band can be completely protected and there is no need to worry about it being tampered with. In addition, it is safe because clothes, hands, etc. will not be caught during other work on the telephone pole.
